The type of element of a particular atom is based solely on its number of protons. An atom with 9 protons has an atomic number of 9, and is (looking on the elemental chart...) fluorine (F).
The element is Neon and the isotope is 10Ne19
Oxygen has 6 protons and 8 neutrons (symbol O).
10 neutrons(uncharged) 10 neutrons(uncharged)
10 Protons 10 Neutrons in the most common isotope.
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
Neon has 10 protons and 9 neutrons.
The element is Neon and the isotope is 10Ne19
11 protons and 9 neutrons
The number of protons gives the element number; element number 9 is Fluorine.
The element is Neon and the isotope is 10Ne19
The element with 9 protons and 10 neutrons is fluorine-19 (F-19).
The mass is protons + neutrons. So, if the mass is 9 and it has 5 neutrons, then there must be FOUR (4) protons. This would be the element beryllium (Be).
Oxygen has 6 protons and 8 neutrons (symbol O).
The nine protons tells you that the atomic number of the element is going to be nine. Element #9 happens to be Fluorine (F). The most common isotope of fluorine has t10 neutrons. If it doesn't have nine protons, though, it isn't fluorine.

Only protons and neutrons have 1 unit mass each, which form the nucleus. The Electrons that orbit the nucleus are of negligable mass. Therefore; total mass = 9 protons + 10 neutrons = 19 unit mass.
That would Beryllium, with an atomic number of 4 and mass number of 9Hope this helped!
